Experimental design of concrete mixtures using recycled ...

2020-9-10  Experimental mixture design The mechanical properties of a concrete mixture can vary greatly depending on its components’ characteristics (e.g., amount, shape, size, deformability, strength, specific gravity, absorption) and the processes of mixing and curing. Moreover, tests of concrete properties can be very expensive and time-consuming.
